Puting color in a black and white picture.

I was wondering if someone could help tell me how to put color in a black and white picture. For instance a red rose or a persons eye color. I am new at photography and like the unusual shots and techniques.

If the image is black and white then have a little practice with food colour. This is much cheaper than the special inks and will wash out if you go wrong. I buy tubs of colour not the bottles, this way I can mix them just like watercolour paints. Once dry they last and just add a hint of colour to flowers etc.
